Maybe someone will invent a cooled water dispensing machine - they could call it something like a “water fountain”
A water cooler lowers the water temperature, while a drinking fountain is intended to drink from the water supply. A water fountain is an architectural appurtenance for aesthetics.
The move to get rid of bottled water is smart from a hygienic perspective. Unlike public water distribution systems, bottled water is not as well regulated to ensure the public safety. Water tends to become more unsanitary the longer it remains idle with just a small amount of biologicals seeking something to feed upon.
A single molecule of water in a public utility system is very likely to be discharged from the tap within a day to a week from the original water source (river, reservoir, stream, well, lake), whereas bottled water is likely to have sitting like Petri dish for months to years.
Surface water must be filtered prior to distribution and unlike a decade or two ago, many, if not most water distribution networks today are made from PVC piping instead of ferrous or steel pipe, with very little influence of corrosion upon the water quality.
As a utility, public water systems are designed to provide a commonly used resource at the least cost.
In summary, it’s stupid not to drink tap water, unless the water sources in your area are polluted, in which case federal law mandates the notification of such hazards to the public.
